NOLAGT;4634496; said:I will keep the divider in mind. I have not bread any kind of parachromis yet but I have these little RTMs and a 5" male and 3" female f1 yellow head freddie from jeff rapps that I have in a 125 gal. Think I would need a divider for the fredies in a 6' tank alone...they get a little bigger than the RTMs right.
